SWING.

Specification of Letters Patent.

Patented March 26, 1907.

Application filed August 31,1904. Serial No. 222,880.

To all whom it may concern.-

Be it known that I, ALLEN P. BOYER, a citizen of the United States,residin at the city of Goshen, county of Elkhart, State of Indiana, haveinvented certain new and useful Improvements in Swings, of which thefollowing is a specification. 5;. This invention relates to improvementsin swings.

It relates particularly to an improved swing in which the, seats moveback and forth without being suspended, such as is illustrated anddescribed in Letters Patent No. 769,298, No. 769,299, issued to me onthe 6th of September, 1904, and is a modification of and in somerespects an improvement upon the structures therein illustrated anddescribed.

The main object of this invention is to provide an improved swing of theclass above described which can be readily moved without disassemblingor disarranging the parts.

Further objects and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawings, forming a part of thisspecification, in which Figure l is a side-elevation view of my improvedswing. Fig. 2 is a side-elevation view of one of the rockers D, showingthe structural details thereof, the same being shown by dotted lines atone end of its movement or stroke. Fig. 3 is an end-elevation view ofthe structure appearing in Fig. 1. Fig. 4 is a detail side-elevationview showin the position of the parts toward one end of the movement orstroke of the swing.

In the drawings similar letters of reference refer to similar partsthroughout the several views.

Referring to the drawings, the platform or base is formed of side railsA, which are connected together or secured in proper relation to eachother by suitable cross-pieces A. The side rails serve to support andguide the swinging parts above. The side rails are provide with ways ontheir upper sides for the double-headed rockers D. These ways areprovided with flanges a, at their outer edges to retain the rockers Dthereon and to guide the same. The inner or guidin faces of theseflanges are inclined, as clear y appears in Fig. 3.

The seats B are carried by a frame, and this frame is supported by therockers D. The seat-carrying frame consists of side bars B, havingupwardly-projecting standards B arranged in pairs at each end. Suitablebraces, as b, are provided for the standards B. Tracks or ways I), whichare adapted to travel upon the}?double-headedErockers D, are providedfor the frame, therebyjsupporting the frame and its attached parts. Theways I) are provided with guiding-flanges 6, corresponding to theflanges a. The flanges b are also provided with inclined guidingfaces,so that the frame is guided upon the roclgers without any tendency ofthe parts to bin The double-headed rockers D are rigidly connectedtogether in pairs by the crosspieces D, D, and d. (See Fig. 3.) Links eand e are pivotally secured to the ways I) and to the side rails or waysof the platform. The links 6 are provided with longitudinal slots 2,which engage the laterally-projecting pin 8 on the inner faces of therockers. The links 6 are provided with longitudinal slots e, whichengage the cross-pieces D of the rockers. These slotted links permit thefree movement of the rockers and serve as stops and assist in retainingthe rockers upon the platform and keeping them properly centered inrelation to each other. The pairs of rockers are also connected togetherby the foot-rest frame C, which is supported by the cross rods or pieces(1 of the rockers. These cross-rods d are preferably located at a pointbelow the center of the rockers. Thus arranged, motion may be impartedto the structure by the user occupying the seat pushing with the feetagainst the foot-rest C, which is carried by the frame C, a slight pushof the foot being sufficient to cause the frame to glide to and fro uponthe rockers.

The curvature of the rockers D is preferably somewhat modified, so thatthey act as brakes toward the end of the movement thereof, therebyrelieving somewhat the strain upon the other parts and serving toslacken the speed of the swing toward the ends of its movement. By thusforming the rockers they always return to a central position when not inuse. A very slight modification of the same, as is illustrated by dottedlines in Fig. 2, is found sufficient.

To secure the seat-carrying frame and platform together, so that therockers will not be lifted from the platform in moving the structure, Iarrange upwardly-curved bars E on the lower ends of the standards'B ofthe frame, so that the bars are reciprocated alongside of the side railsof the platform, as clearly appears from the drawings. Hooks E, whichproject outwardly over the side bars, are centrally arranged on theplatform. Thus arranged the whole structure may be lifted by theseat-carrying frame without danger of disarranging the parts. These barsand hooks also serve as stops to limit the movement of the rockers.Owing to the slight upward lift of the seat-carrying frame by therockers at the end of the movement thereof, the bars E are liftedupwardly against the hooks E, thereby stopping the movement in thatdirection. These parts can be readily made of comparatively heavymaterial, so that they are not injured, although the swing may be movingwith considerable force. The stops are also in such positionthat themovement is checked with comparatively little strain on the parts. It isevident that were rockers employed in which the curvature was notmodified as is illustrated it would not be desirable to curve the bar E,as in case it were curved the hooks E would not properly secure theparts together for transportation. It is evident that the form of theseparts might be greatly modified and still secure substantially the sameresults.

By the arrangement of the parts as I have illustrated and described Isecure a swing which may be operated with comparatively slight exertionand one which is very compact in structure, and although comparativelylight in weight it is rigid and durable and capable of carrying heavyloads without injury thereto.

I have illustrated and described my improved swing in detail in the formpreferred by me on account of its simplicity and the economy ofconstruction. I am, however, aware that it is capable of considerablestructural variation without departing from my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
